Sprocket Ratio Calculator

Formula

To calculate the Sprocket Ratio (SR):

\[ SR = \frac{T_{driving}}{T_{driven}} \]

Where:

\(SR\) is the Sprocket Ratio
\(T_{driving}\) is the number of teeth on the driving sprocket
\(T_{driven}\) is the number of teeth on the driven sprocket

What is the Sprocket Ratio?

The Sprocket Ratio (SR) is a measure used to determine the relationship between the number of teeth on the driving sprocket and the driven sprocket. It helps in understanding the mechanical advantage and speed ratio between the two sprockets[^1^][^2^].

Example Calculation 1

Let's assume the following values:

Number of Teeth on Driving Sprocket (\(T_{driving}\)) = 20
Number of Teeth on Driven Sprocket (\(T_{driven}\)) = 40

Using the formula:

\[ SR = \frac{20}{40} = 0.5 \]

The Sprocket Ratio is 0.5.

Example Calculation 2

Let's assume the following values:

Number of Teeth on Driving Sprocket (\(T_{driving}\)) = 15
Number of Teeth on Driven Sprocket (\(T_{driven}\)) = 30

Using the formula:

\[ SR = \frac{15}{30} = 0.5 \]

The Sprocket Ratio is 0.5.
